For sure that enough light, thats more than enough light if used wisely. The leafs pointing up is not a problem! This is your plant finally thanking you for not over watering it for once. With those CFLs more light comes of the sides. I would place the one 85 watt on it's side, with a reflector, 2 inches from the top of the plant and those 42's around the sides, aslo with reflector made from beer cans. Don't listen to DR. Greenthumb, you already said you have height restrictions so growing a big ass plant isn't an option. With these three light you could grow 3 small females which would achieve the maximum amount of pot for those watts. Also Don't harvest yet, your plants sure don't look 6 or 7 weeks into flowering, they look about 4 maybe 5, notice the lack of any orange hairs. I'm guessing you started flowering prematurely. Now this is not bad, it only means the plant continued to veg despite the 12 and 12 cycle because the plant needs to attain a certain maturatiy before it can flower, no matter what light cycle. Add another 2 to 3 weeks to your flowering time. Get some bad Guano, and some Molasses, and just keep doing what your doing.
For more the most part looks good.
My grow cabinet is 21" by 30"
